Saturn moon's underground ocean captured by Nasa spacecraft – video

Nasa's Cassini spacecraft captures images of Saturn moon's underground ocean. The spacecraft's close flyby of icy moon Enceladus reveals more about the deep saltwater ocean hidden inside the planet which was discovered last year by researchers. The images show the pale, grooved and cratered surface of the moon, and several bright streaks of vapour plumes erupting from its south pole. Photograph: AP
